    Why there seem to be no liquid or room-temperature sodium-ion conductors?
    And sodium-sulfur batteries are forced to use solid beta-alumina electrolyte
    which conducts at 300 centigrads?Is there some sodium salts similar to NaCl
    which conduct sodium ions when get dissolved at room temperature?
    Is it true that very thin pieces of beta-alumina are much more conductive
    and would allow conduction at room temperature?There is some attempts to
    create room temperature sodium-sulfur battery with energy density 300 Wh/kg.
    They hope to use beta-alumina electrolyte of few micron thickness.

    Or this is rather scum?
    If this is true,will Sodium-Sulfur become an ultimate battery,having highest energy density
    at affordable cost from all the batteries?

    May be its true that it has high energy density and made from cheap metirials but maintainance of those batteriess is not affordable at present

    the batteries get high energy and power density because of molten salt electrolytes so its impossible for them to work at room temperature at present.
